GENERAL Introduction
The present CLAAS REPAIR MANUAL is intended to
assist in preserving the permanent operational readi-
ness and therefore the high value of your CLAAS com-
bine harvester by thorough maintenance and service
supervision.
Experience gathered by both our service engineers
and factory staff has been compiled in this REPAIR
MANUAL.
The sequences of pictures illustrate the course of a
repair process while the text provides the necessary
information on adjustments, application of CLAAS spe-
cial tools and the like.
The illustrations included in support to the explana-
tions show the sequence of major repairs so that
minor repairs can easily be followed.
The CLAAS REPAIR MANUAL is filled in a folder
which allows to insert supplementary pages as issued
following technical developments and to always have
an updated manual at hand for reference.
To be sure, always compare settings and filling capac-
ities with specifications stated in the current Operator's
Manual of the combine-harvester.

General

Introduction into the CLAAS Repair Manual The CLAAS Repair Manual is subdivided into main
groups and subgroups.
The first digit of the number to be found at the bottom
of each page indicates the main group, the digit follow-
ing the first dot indicates the subgroup and the digit fol-
lowing the second dot the page number. Both pictures
and pages are numbered consecutively in each sub-
group, starting at 1.
Differences between the machine types are high-
lighted by captions or headings. Mechanical proce-
dures applying to all machine types covered in this
manual are kept neutral.
Supplements are realised by adding and/or replacing
the subgroups. Any supplements are filed in the
respective main group / subgroup and the table of con-
tents is updated.
The pictorials serve for quick orientation in recurring
mechanical procedures. Their meanings are explained
at the beginning of this manual.
The "GENERAL REPAIR INFORMATION" section at
the beginning of this manual contains informative
explanations. Read and follow this important informa-
tion. This is the basis of safe and continued function
following a repair.
The table of contents of the main group / subgroup
in question will allow you to locate any mechanical
work description quickly.

SAFETY RULES Important note

The instructions contained in this manual
should be carefully read and observed by all
persons involved with the operation, mainte-
nance and inspection of this machine in order
to prevent accidents. In particular, read the sec-
tion "Safety rules".
The use of spare parts, accessories and ancil-
lary equipment other than genuine CLAAS prod-
ucts or those which have been tested and
approved by CLAAS, may change the specified
design characteristics of this CLAAS machine
or detract from its functional performance, with
a possible adverse effect on the active and/or
passive operational safety of the machine and
its occupational safety standards (accident pre-
vention).
CLAAS is in no way liable for any damage or
personal injury caused through the use of other
than original or approved CLAAS parts, acces-
sories and ancillary equipment.
Technical data, dimensions and weights are
without obligation. CLAAS reserve the right to
make changes subsequently as technical devel-
opments continue. Responsibility for errors or
omissions not accepted.
Front, rear, right and left refer to the direction
of forward travel.

serious infections may result!
3. Always turn off the battery isolating switch
before carrying out any electrical repairs on
the machine!
4. Be careful when opening the radiator cap.
As long as the engine is hot, the radiator is
under pressure!
5. Dispose of oil, fuel and filters in a way that is
harmless to the environment and in accordance
with existing anti-pollution regulations!
6. Do not attempt to mount a tyre unless you
have the proper equipment and experience
to perform the job safely.
7. Retighten the wheel nuts regularly!
8. Only have qualified workshops carry out repair
work on the hydraulic system.

Attention!

Any deviating tightening torques reduce the

rated pressure resistance and the service life
of the screw fitting. This results in leaks and
the tube slipping out.

Welding Work

Attention!

When carrying out electric welding work on

the machine, observe the following points:
1. Disconnect the battery isolating switch!
2. Disconnect the monitor connector.
3. Remove the electric plug-in type modules located
in the central terminal compartment.
4. Disconnect the electric connectors between the
engine and the main wiring loom.
5. Always connect the ground clamp of the welders
in the immediate vicinity of the welding point.

Some advice for speedy and correct repair

work:
– Mark machine parts prior to disassembly to
ensure their correct left-to-right positions and bal-
ance when reassembled.
– Fit expansion pins with the slot facing the side
under load. When fitted with a quarter turn from
this position, they will get loose, fall out or shear
off.
– Replace split pins, locking wires, locking plates,
tab washers and lock washers when carrying out
repairs.
– Insert greasable ball and sliding bearings with
good grease.
– Align sprockets and V-belt pulleys toward each
other.
